Success of the prosthesis after mandibular resection is related directly to the amount of the remaining bone and soft tissue present. The prognosis for mandibulectomy patients becomes less favorable as the size of the resection increases. Prosthetic rehabilitation for such patients is a challenge for clinicians. Without preprosthetic reconstructive surgery, denture fabrication for mandibulectomy patients becomes extremely difficult. Telescopic dentures is a modality of treatment consisting of an inner or primary telescopic coping which is permanently cemented to an abutment and an outer or secondary telescopic coping which is attached to the prosthesis. These copings protect the abutment from dental caries and thermal irritations and also provide retention and stabilization of the secondary coping. The secondary coping engages the primary copings to form a telescopic unit and it provides retention and stability to the prosthesis. This clinical report aims at utilizing the remaining natural teeth for a mandibular overdenture with telescopic coping. 相似文献

The primary objectives of successful prosthetic rehabilitation are to provide function, esthetics and comfort to the patient. Combination prosthesis is one which is supported by both natural teeth and implant. The periodontal ligament and osseointegrated interface distribute force differently to the supporting bone. Therefore problems can develop when tooth and implants are combined in the same prosthesis. However, clinicians can apply biomechanical principles, to negate the deleterious leverages exerted by the fixed prosthesis by using non rigid components and to equalize the stress applied by the prosthesis on implant and teeth. A case of partially edentulous situation was rehabilitated successfully with a combination of prostheses. Maxillary arch was restored to function with crowns, fixed dental prosthesis and with an extra coronal castable attachment prosthesis and the mandibular arch with a combination of tooth and implant supported attachment prosthesis. The clinical and laboratory steps for the fabrication of these prostheses are explained in this report. 相似文献

This is a clinical report of a patient who was not referred for prosthodontic evaluation and treatment until after undergoing Bränemark endosseous implant placement to supplement the previously existing mandibular staple bone plate implant. This supplemental treatment was the surgeon's attempt to resolve the patient's complaint of loose dentures. Creativity with implant biomechanics and prosthodontic design were necessary to restore the patient, in a predictable manner, to normal function. A fixed, detachable cast overdenture bar rigidly connected to all the implants was constructed utilizing resilient attachments to retain the tissue-supported mandibular overdenture. A presurgical prosthodontic evaluation could have averted many of the problems encountered with treatment. More effective conventional prosthodontic treatment may have resolved the patient's complaints and eliminated the need for additional implant placement. 相似文献

Acromegaly is an adult endocrine disorder that results from excessive growth hormone after closure of the growth plates and is associated with significant morbidity and increased mortality. The orofacial features of patients with acromegaly are thick lips with a tendency towards mandibular overgrowth with prognathism, jaw thickening, maxillary widening, drifting of teeth, malocclusion, and increased gonial angle, all of which can challenge the prosthodontist in dental rehabilitation. Additionally, excessive secretion of growth hormone and insulin‐like growth factors have been shown to increase bone turnover, which in turn leads to weakening of bone microarchitecture and high risk of fragility fractures. This clinical report describes the 4‐year follow‐up of a 59‐year‐old white male with acromegaly, who was managed successfully by using dental implants for replacing his missing teeth. Considerations related to treatment planning, implant surgery, bone remodeling, and management of dental occlusion are discussed. This is the first clinical report in the dental literature describing the use of dental implants in an acromegaly patient. 相似文献

Residual ridge resorption is a rapid, progressive, irreversible, and inevitable process of bone resorption. Long‐standing teeth and implants have been shown to have maintained the bone around them without resorption. Thus, overdenture therapy has been proven to be beneficial in situations where few remaining teeth are present. In addition to the various advantages seen with tooth‐supported telescopic overdentures, a few shortcomings can also be expected, including unseating of the overdenture, increased bulk of the prosthesis, secondary caries, etc. The precise transfer of the secondary telescopic copings to maintain the spatial relationship, without any micromovement, remains the most critical step in ensuring the success of the tooth‐supported telescopic prosthesis. Thus, a simple and innovative technique of splinting the secondary copings was devised to prevent distortion and micromovement and maintain its spatial relationship. 相似文献

Pemphigus vulgaris (PV) is a rare mucocutaneous vesiculobullous disease characterized by the development of autoantibodies against the desmosomal proteins. Current treatment is largely based on systemic immunosuppression using systemic corticosteroids. Immunosuppressive drugs used in the treatment of the disease may increase the risk of infection and delayed healing, which are of concern in dental treatment procedures in this group of patients. The clinical outcomes of implants in PV have not been investigated. We present a case of PV rehabilitated with an implant‐supported prosthesis with a 32‐month follow‐up and discuss the important points in the surgical and prosthodontic phases. 相似文献

Implant‐Supported Obturator Overdenture for Extensive Maxillary Resection Patient: A Clinical Report
Cláudio Rodrigues Leles DDS PhD José Luiz Rodrigues Leles DDS PhD Carlos de Paula Souza DDS PhD Rafael Ragonezi Martins DDS MSc Elismauro Francisco Mendonça DDS PhD 《Journal of prosthodontics》2010,19(3):240-244
This clinical report presents an implant‐retained obturator overdenture solution for a Prosthodontic Diagnostic Index Class IV maxillectomy patient with a large oronasal communication and severe facial asymmetry, loss of upper lip and midfacial support, severe impairment of mastication, deglutition, phonetics, and speech intelligibility. Due to insufficient bone support to provide satisfactory zygomaticus implant anchorage, conventional implants were placed in the body of the left zygomatic arch and in the right maxillary tuberosity. Using a modified impression technique, a cobalt‐chromium alloy framework with three overdenture attachments was constructed to retain a complete maxillary obturator. Patient‐reported functional and quality of life measure outcomes were dramatically improved after treatment and at the two‐year follow‐up. 相似文献

Clefts of the lip and/or palate (CLP) are oral‐facial defects that affect health and overall quality of life. CLP patients often need multidisciplinary treatment to restore oral function and esthetics. This paper describes the oral rehabilitation of a CLP adult patient who had maxillary bone and tooth loss, resulting in decreased occlusal vertical dimension. Functional and cosmetic rehabilitation was achieved using a maxillary removable partial denture (RPD) attached to telescopic crowns. Attachment‐retained RPDs may be a cost‐effective alternative for oral rehabilitation in challenging cases with substantial loss of oral tissues, especially when treatment with fixed dental prostheses and/or dental implants is not possible. 相似文献

For most of the last century, conventional complete dentures have been the standard of care and the most common treatment for edentulous patients. Technological advancements in fabrication techniques may significantly reduce the number of office visits required to fabricate complete dentures. Immediate occlusal loading with mandibular full arch prostheses has been extensively researched and is now one of the standards of care for edentulous patients. A clinical technique for converting a mandibular immediate complete denture to an interim full arch, screw‐retained fixed prosthesis with novel implant restorative components for immediate loading on four implants is described. 相似文献

Late cluster implant failures can be one of the most devasting outcomes of implant therapy for patients. It can have anatomic, functional, psychological and financial consequences for patients, and sometimes the loss of residual bone can preclude subsequent implant placement. Fortunately, management of cluster implant failures in the maxilla can be mitigated by using implant anchorage from remote sites like zygomatic and pterygoid regions. Few reports exist in the literature that have described the management of cluster implant failure using extra‐maxillary implants such as zygomatic and pterygoid implants. This case report describes the management of a female patient with bruxism who experienced late cluster implant failure in the maxilla after 9 years of function with an overdenture. Due to the loss of residual bone, subsequent implant therapy involved the use of bilateral zygomatic, pterygoid and anterior maxillary implants, which were immediately loaded and thereafter used to support a complete arch fixed implant‐supported zirconia prosthesis. 相似文献

Various attachment systems have been used to facilitate the retention, stability, and support of overdentures. The low profile design, pivoting technology, and durability of the Locator attachment made it one of the commonly used tissue‐supported implant‐retained overdentures. It has been successfully used to retain overdentures as well as partial dentures. This article describes the uses of the new Locator R‐Tx abutment and illustrates both the direct and indirect techniques used to process the denture attachment housing into the prosthesis to retain overdentures and partial dentures. 相似文献

Two clinical reports present an alternative design to address the problem of unfavorable implant angulations if a screw‐retained prosthesis is desired. The restorations were designed as screw‐retained prostheses, except in the area with the unfavorable implant screw emergence. The frameworks in these areas were customized to receive individual cement‐retained crowns. This design offers retrievability and helps to minimize complications associated with excess cement without compromising the functional or esthetic outcome. 相似文献

Despite advancements in restorative materials and techniques, complications with implant‐supported fixed prostheses such as veneer fracture and material wear are very common and present with varying frequencies. Following these complications, repair of this type of prosthesis can be time‐consuming and costly even in the hand of experience clinicians. Several techniques have proposed using the existing framework to minimize the cost of the repair for the patient; however, while the repairs are being performed, the patient will have to either wear an interim complete denture or no prosthesis, which might cause some inconvenience to the patient. This article will present a technique for the fabrication of a metal‐reinforced interim implant‐supported fixed prosthesis for patients to wear while the existing prosthesis is being repaired. 相似文献
